Only having the arrow keys working is the normal symptom of lirc not
working at all and mythfrontend getting keystrokes directly from the
devinput driver.  The arrow keys are normally the only ones that are
mapped to something that mythfrontend responds to.  Maybe the number
keys will also work.  I would suggest trying the irw program to see if
there is any output from the lirc socket when you press a remote
button.  I am guessing that there will be nothing.
